The AirTAC GC40010LF2K AirTAC F.R.L. Combination, PT3/8 is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT3/8" ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010LF2K is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This size 400 unit has PT3/8 ports and filters to the standard 40 um grade, with a differential-pressure drain on the filter bowl. The regulator is the low-pressure type, fitted with an embedded square gauge reading in psi, and a reverse/check valve is fitted to hold downstream pressure when the supply is lost. Bowls are polycarbonate at this size, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part. The GC line is available in sizes 200, 300, 400 and 600 with a choice of ports, threads, drains, filter grades, gauge scales and regulator types, so a configuration can be matched to most compressed-air circuits. Because flow is published as curves rather than a single rating, we confirm the datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF400-10 filter, GR400-10 regulator and GL400-10 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Feeds a row of impact tools and air cylinders at a car-plant assembly station: the filter dries and cleans the drop, the low-pressure regulator sets the working pressure for the tools, and the lubricator mists oil into the tool feed lines.
Supplies the pneumatic cylinders on a carton-forming and sealing machine, where the reverse/check valve holds the set pressure if the shop-air supply drops and the lubricator keeps the cylinder seals working over long production runs.
Conditions the supply to a bench-top test rig or pilot plant: the 40 um filter keeps particulate and water out of sensitive instruments, the low-pressure regulator trims the supply down for the rig, and the gauge gives a local psi readout.
Start with the port step: this unit is size 400 with PT3/8 ports, one step up from 1/2 in alternatives in the range if your circuit needs more capacity - match the size to the air demand of the machine rather than the pipe alone. The filter carries the standard 40 um element; if the application needs finer filtration, the 5 um (W) grade is available in the same series. The differential-pressure drain bleeds the bowl automatically as pressure drops across the element, so no daily manual draining is needed. The low-pressure regulator suits circuits that run well below standard line pressure; its exact adjustment range is not published in the catalogue, so ask us to confirm it before ordering. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are options. Thread is PT as standard, with G (BSPP) and NPT available to order, and a bracket is included.
Flow for this series is published as curves, not a single rated figure, so send us your air demand and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number. Send us your air demand and line conditions and we will confirm the sizing against the datasheet on request before you order.
K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply is lost. The filter bowl uses a differential-pressure drain, which bleeds collected water automatically as the pressure drop across the element changes - no manual draining is required.
